WED Assessment

What are sediments?

• Small sections of tectonic plates

• Small pieces of rock or soil material

• The new minerals created after chemical weathering

• The new land created by deposition

Which of the following is not an example of mass movement?

• Landslides

• Acid rain

• Mudflow

• Slump

Frost wedging, root wedging, exfoliation, abrasion, and thermal expansion are all

examples of which of the following processes?

• Mechanical weathering

• Chemical weathering

• Erosion

• Deposition

Which of the following lists the four agents of chemical weathering?

• Hydrogen, oxygen, carbon dioxide, deposition

• Water, water vapor, ice, glacial movement

• Water, wind, fire, oxygen

• Water, carbon dioxide, oxygen, acid produced by decaying plants and animals

All of the following processes cause erosion on Earth’s surface except -

• Volcanic activity

• Waves

• Wind

• Moving water

The burning of fossil fuels contributes to which of the following?

• Mechanical weathering

• Lower levels of carbon dioxide in the atmosphere

• Acid rain

• Deposition of sediments

How do glaciers contribute to the process of deposition?

• As glaciers melt they leave behind sediment

• As glaciers melt they collect sediment

• As glaciers move they pick up and carry away rocks

• As glaciers move they break down rocks

How does the composition of a rock affect its rate of weathering?

• The more dense the rock, the faster it will weather

• The less dense the rock, the slower it will weather

• Many rocks contain different minerals that will weather at different rates

• All rocks weather at the same rate regardless of composition

The process of breaking down rock on Earth’s surface.

• Abrasion

• Sediment

• Weathering

The process by which water, ice, wind, or gravity moves pieces of rock or soil.

• Delta

• Erosion

• Sediment
